Bacteria to the Rescue: Using Microorganisms to Create Nano-Technology


A single computer used to fill an entire room. Now, the processors in most smartphones are greater than those of the first mega-computers. But, as technology gets smaller and smaller, it gets more and more difficult to produce "nano-sized" electronics.

So scientists have decided to get nature involved.  Scientists at the University of Leeds in the UK and at Japan's Tokyo University of Agriculture and Technology are using a special form of bacterium to test their theory. The microorganisms - Magnetospirillum magneticum -  naturally create tiny magnetic crystals when they ingest iron. These magnets are similar to those found in PC hard drives.

 In addition to production, scientists are also studying the way the bacteria align and organize the nano-magnets. Studying "nature's machines" has provided a more streamlined method for future electronics advancement.


These scientists are also using living organisms to create nano-scale tubes. Like a cell membrane, these tubes would be capable of transferring information inside a computer.

Just think - in a few years, your computer could be built by bacteria and wired together by cell membranes. The changing pace of technology is amazing.
